LANSING - A 20-year-old Olivet woman whose child suffered serious injuries told police she threw her infant son into a playpen on several occasions.

Taylor Prahl-Six's 2-month-old son was admitted to the Intensive Care Unit at Sparrow Hospital in early July with two brain bleeds and a skull fracture, Eaton County Sheriff's Office Detective Theodore Johnson testified in a hearing that led to criminal charges being filed.

An MRI of the baby showed blood in his spinal cord, which is suggestive of shaken baby syndrome, Johnson said to a court official.

The boy had a skull fracture and two brain bleeds, one old and one new, when he was admitted to the hospital July 3. Concerned family members brought the boy to the hospital.

Prahl-Six told police she had thrown her son "forcefully" into the playpen out of frustration on several occasions, Johnson said. During a polygraph, she said she had also shaken him several times.

She was charged with first-degree child abuse and was arrested July 20. She remained in the Eaton County Jail as of Tuesday morning on a $100,000 bail. She is set to appear in court Aug. 3.
